Various methods have been used to treat phantom limb pain. Doctors may prescribe medications to reduce the pain. Some antidepressants or antiepileptics have been shown to have a beneficial effect on reducing phantom limb pain. Often physical methods such as light massage, electrical stimulation, and hot and cold therapy have been used with variable results.

There are many different treatment options for phantom limb pain that are actively being researched. Most treatments do not take into account the mechanisms underlying phantom pains, and are therefore ineffective. However, there are a few treatment options that have been shown to alleviate pain in some patients, but these treatment options usually have a success rate less than 30%. It is important to note that this rate of success does not exceed the placebo effect. It is also important to note that because the degree of cortical reorganization is proportional to phantom limb pains, any perturbations to the amputated regions may increase pain perception.

Mirror box therapy allows for illusions of movement and touch in a phantom limb by inducing somatosensory and motor pathway coupling between the phantom and real limb. Many patients experience pain as a result of a clenched phantom limb, and because phantom limbs are not under voluntary control, unclenching becomes impossible. This theory proposes that the phantom limb feels paralyzed because there is no feedback from the phantom back to the brain to inform it otherwise. Vilayanur S. Ramachandran believes that if the brain received visual feedback that the limb had moved, then the phantom limb would become unparalyzed.

Although the use of mirror therapy has been shown to be effective in some cases there is still no widely accepted theory of how it works. In a 2010 study of phantom limb pain, Martin Diers and his colleagues found that "In a randomized controlled trial that used graded motor imagery...and mirror training, patients with complex regional pain syndrome or phantom limb pain showed a decrease in pain as well as an improvement in function post-treatment and at the 6-month follow-up. And it was shown that the order of treatment mattered." This study found that mirrored imagery produced no significant cortical activity in patients with phantom limb pain and concluded that "The optimal method to alter pain and brain representation, and the brain mechanisms underlying the effects [of] mirror training or motor imagery, are still unclear."

A number of small scale research studies have shown encouraging results, however there is no current consensus as to the effectiveness of mirror therapy. Recent reviews of the published research literature by Mosely and Ezendam concluded that much of the evidence supporting mirror therapy is anecdotal or comes from studies that had weak methodological quality. In 2011, a large scale review of the literature on mirror therapy by Rothgangel summarized the current research as follows:

Most approaches to treatment over the past two decades have not shown consistent symptom improvement. Treatment approaches have included medication such as antidepressants, spinal cord stimulation, vibration therapy, acupuncture, hypnosis, and biofeedback. Reliable evidence is lacking on whether any treatment is more effective than the others.

Most treatments are not very effective. Ketamine or morphine may be useful around the time of surgery. Morphine may be helpful for longer periods of time. Evidence for gabapentin is mixed. Perineural catheters that provide local anesthetic agents have poor evidence when placed after surgery in an effort to prevent phantom limb pain.

One approach that has received public interest is the use of a mirror box. The mirror box provides a reflection of the intact hand or limb that allows the patient to "move" the phantom limb, and to unclench it from potentially painful positions.

As of 2011, however, the quality of evidence is low. There is a wide range in the effectiveness of this approach. The potential for a person to benefit from mirror therapy is not predictable and appears to be related to the subjective ability of the patient to internalize the reflection of a complete limb as their own limb. About 40% of people do not benefit from mirror therapy.

As of 2013 low quality evidence supports the use of bisphosphonates. A 2009 review found "very limited data reviewed showed that bisphosphonates have the potential to reduce pain associated with bone loss in patients with CRPS I, however, at present there is not sufficient evidence to recommend their use in practice".

Spinal cord stimulator) appears to be an effective therapy in the management of patients with CRPS type I (Level A evidence) and type II (Level D evidence). While they improve pain and quality of life evidence is unclear regarding effects on mental health and general functioning.

Daily oral muscle physical therapy, or the administration of antidepressants have been reported as effective therapy for occlusal dysesthesia patients. Tooth grinding, and the replacement or removal of all dental work should be avoided in patients with occlusal dysesthesia, despite the frequent requests for further surgery often made by these patients.

Antidepressants are also often prescribed for scalp dysesthesia.

Prakash et al. found that many patients suffering from burning mouth syndrome (BMS), one variant of occlusal dysesthesia, also report painful sensations in other parts of the body. Many of the patients suffering from BMS met the classification of restless leg syndrome (RLS). About half of these patients also had a family history of RLS. These results suggest that some BMS symptoms may be caused by the same pathway as RLS in some patients, indicating that dopaminergic drugs regularly used to treat RLS may be effective in treating BMS as well.

A theoretical explanation for the mechanism of pain reduction by transcranial electrostimulation, or TCES, suggests that the electrical stimulation activates the anti-nociceptive system in the brain, resulting in β-endorphin, serotonin and noradrenaline release. TCES can be used on people with cervical pain, chronic lower back syndrome, or migraines. It cannot be used on people with orthopedic or radiological potentially serious spinal conditions, hydrocephalus, epilepsy, glaucoma, malignant hypertension, pacemaker or other implanted electronic device; recent cerebral trauma, nervous system infection, skin lesions at sites of electrode placement; oncological disease; patients undergoing any other treatments for pain; any invasive therapy, e.g. surgery, within the last month. The equipment used is Pulse Mazor Instruments' Pulsatilla 1000, which consists of a headset with three electrodes, two that go behind the ears and one that goes on the forehead, that release set frequencies of electricity at set intervals.

Pain is the most common reason for people to use complementary and alternative medicine. An analysis of the 13 highest quality studies of pain treatment with acupuncture, published in January 2009, concluded there was little difference in the effect of real, faked and no acupuncture. However, other reviews have found some benefit. Additionally, there is tentative evidence for a few herbal medicines. There has been some interest in the relationship between vitamin D and pain, but the evidence so far from controlled trials for such a relationship, other than in osteomalacia, is inconclusive.

A 2003 meta-analysis of randomized clinical trials found that spinal manipulation was "more effective than sham therapy but was no more or less effective than general practitioner care, analgesics, physical therapy, exercise, or back school" in the treatment of lower back pain.

Deep brain stimulation, or DBS, was first evaluated as an electroanalgesic in the late 1950s. It works in some chronic pain patients. The mechanism of DBS is unknown. There is some evidence that it decreases pain transmission along sensory discriminative pathways although more recent studies have shown that it has central effects on other brain regions involved in the pain network (Pereira et al. 2007). This method has mainly been used for chronic pain patients after all other options have failed due to potential of intracranial complications (e.g., intracranial hemorrhage, infection, and oculomotor abnormalities). An electrode is "stereotactically" guided to the site using magnetic resonance imaging and once in place, the electrode is activated by subcutaneous leads attached to a pulse generator under the skin. It is effective in treating refractory post-stroke pain, atypical face pain, anaesthesia dolorosa, and deafferentation and somatic pain such as in phantom limb or brachial plexus injury (Boccard et al. 2013).

Individuals with more social support experience less cancer pain, take less pain medication, report less labor pain and are less likely to use epidural anesthesia during childbirth, or suffer from chest pain after coronary artery bypass surgery.

Suggestion can significantly affect pain intensity. About 35% of people report marked relief after receiving a saline injection they believed to be morphine. This placebo effect is more pronounced in people who are prone to anxiety, and so anxiety reduction may account for some of the effect, but it does not account for all of it. Placebos are more effective for intense pain than mild pain; and they produce progressively weaker effects with repeated administration. It is possible for many with chronic pain to become so absorbed in an activity or entertainment that the pain is no longer felt, or is greatly diminished.

Cognitive behavioral therapy (CBT) has been shown effective for improving quality of life in those with chronic pain but the reduction in suffering is modest, and the CBT method was not shown to have any effect on outcome. Acceptance and Commitment Therapy (ACT) may also effective in the treatment of chronic pain.

A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain under some conditions, though the number of patients enrolled in the studies was low, raising issues related to the statistical power to detect group differences, and most lacked credible controls for placebo or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."

The management of low back pain often includes medications for the duration that they are beneficial. With the first episode of low back pain the hope is a complete cure; however, if the problem becomes chronic, the goals may change to pain management and the recovery of as much function as possible. As pain medications are only somewhat effective, expectations regarding their benefit may differ from reality, and this can lead to decreased satisfaction.

The medication typically recommended first are NSAIDs (though not aspirin) or skeletal muscle relaxants and these are enough for most people. Benefits with NSAIDs; however, is often small. High-quality reviews have found acetaminophen (paracetamol) to be no more effective than placebo at improving pain, quality of life, or function. NSAIDs are more effective for acute episodes than acetaminophen; however, they carry a greater risk of side effects including: kidney failure, stomach ulcers and possibly heart problems. Thus, NSAIDs are a second choice to acetaminophen, recommended only when the pain is not handled by the latter. NSAIDs are available in several different classes; there is no evidence to support the use of COX-2 inhibitors over any other class of NSAIDs with respect to benefits. With respect to safety naproxen may be best. Muscle relaxants may be beneficial.

If the pain is still not managed adequately, short term use of opioids such as morphine may be useful. These medications carry a risk of addiction, may have negative interactions with other drugs, and have a greater risk of side effects, including dizziness, nausea, and constipation. The effect of long term use is unknown. Specialist groups advise against general long-term use of opioids for chronic low back pain.

For older people with chronic pain, opioids may be used in those for whom NSAIDs present too great a risk, including those with diabetes, stomach or heart problems. They may also be useful for a select group of people with neuropathic pain.

Antidepressants may be effective for treating chronic pain associated with symptoms of depression, but they have a risk of side effects. Although the antiseizure drugs gabapentin and carbamazepine are sometimes used for chronic low back pain and may relieve sciatic pain, there is insufficient evidence to support their use. Systemic oral steroids have not been shown to be useful in low back pain. Facet joint injections and steroid injections into the discs have not been found to be effective in those with persistent, non-radiating pain; however, they may be considered for those with persistent sciatic pain. Epidural corticosteroid injections provide a slight and questionable short-term improvement in those with sciatica but are of no long term benefit. There are also concerns of potential side effects.

Dysesthesia (or dysaesthesia) comes from the Greek word "dys", meaning "not-normal" and "aesthesis", which means "sensation" (abnormal sensation). It is defined as an unpleasant, abnormal sense of touch. It often presents as pain but may also present as an inappropriate, but not discomforting, sensation. It is caused by lesions of the nervous system, peripheral or central, and it involves sensations, whether spontaneous or evoked, such as burning, wetness, itching, electric shock, and pins and needles. Dysesthesia can include sensations in any bodily tissue, including most often the mouth, scalp, skin, or legs.

It is sometimes described as feeling like acid under the skin. Burning dysesthesia might accurately reflect an acidotic state in the synapses and perineural space. Some ion channels will open to a low pH, and the acid sensing ion channel has been shown to open at body temperature, in a model of nerve injury pain. Inappropriate, spontaneous firing in pain receptors has also been implicated as a cause of dysesthesia.

Patients suffering from dysesthesia can become incapacitated with pain, despite no apparent damage to the skin or other tissue. Patients suffering from dysesthesia also often suffer from psychological disorders.

Exercise appears to be useful for preventing low back pain. Exercise is also probably effective in preventing recurrences in those with pain that has lasted more than six weeks. Medium-firm mattresses are more beneficial for chronic pain than firm mattresses. There is little to no evidence that back belts are any more helpful in preventing low back pain than education about proper lifting techniques. Shoe insoles do not help prevent low back pain.

Treatment of people believed to have ATN or TN is usually begun with medication. The long-time first drug of choice for facial neuralgia has been carbamazepine, an anti-seizure agent. Due to the significant side-effects and hazards of this drug, others have recently come into common use as alternatives. These include oxcarbazepine, lamotrigine, and gabapentin. A positive patient response to one of these medications might be considered as supporting evidence for the diagnosis, which is otherwise made from medical history and pain presentation. There are no present medical tests to conclusively confirm TN or ATN.

If the anti-seizure drugs are found ineffective, one of the tricyclic antidepressant medications such as amitriptyline or nortriptyline, may be used. The tricyclic antidepressants are known to have dual action against both depression and neuropathic pain. Other drugs which may also be tried, either individually or in combination with an anti-seizure agent, include baclofen, pregabalin, anti-seizure drugs (to calm nerve endings), muscle relaxants, and opioid drugs such as oxycodone or an oxycodone/paracetamol combination.

For some people with ATN opioids may represent the only viable medical option which preserves quality of life and personal functioning. Although there is considerable controversy in public policy and practice in this branch of medicine, practice guidelines have long been available and published.

There is moderate quality evidence that suggests the combination of education and exercise may reduce an individual's risk of developing an episode of low back pain. Lesser quality evidence points to exercise alone as a possible deterrent to the risk of the onset of this condition.

The evidence for surgical therapy is poor. Surgery is normally recommended only after medication has proved ineffective, or if side effects of medication are intolerable. While there may be pain relief after surgery, there is also a considerable risk of side effects, such as facial numbness after the procedure. Microvascular decompression appears to result in the longest pain relief. Percutaneous radiofrequency thermorhizotomy may also be effective as may stereotactic radiosurgery; however the effectiveness decreases with time.

Surgical procedures can be separated into non-destructive and destructive:

Expensive and invasive, the above treatments are not guaranteed to work, and are not meeting the needs of patients. There is a need for a new, less expensive, less invasive form of treatment, two of which are postulated below.

- Spinal cord stimulation has been studied in the last couple of years. In a long case study, 8 patients were given spinal cord stimulation via insertion of a percutaneous lead at the appropriate level of the cervical or thoracic spine. Between 36 and 149 months after the stimulations, the patients were interviewed. 6 of the 8 had received initial pain relief, and three experienced long-term pain relief. Spinal cord stimulation is cheaper than brain stimulation and less invasive, and is thus a more promising option for pain treatment.

- In 2007, Dr. V. S. Ramachandran and his lab proposed that caloric stimulation might be effective in treating Dejerine–Roussy syndrome. They hypothesized that if cold water was streamed into the ear down the auditory canal, the symptoms associated with Dejerine–Roussy syndrome would be alleviated. Ramachandran stated that he had carried out provisional experiments on two patients and believed that their reactions supported his theory.

Many chemical medications have been used for a broad range of neuropathic pain including Dejerine–Roussy syndrome. Symptoms are generally not treatable with ordinary analgesics. Traditional chemicals include opiates and anti-depressants. Newer pharmaceuticals include anti-convulsants and Kampo medicine. Pain treatments are most commonly administered via oral medication or periodic injections. Topical In addition, physical therapy has traditionally been used alongside a medication regimen. More recently, electrical stimulation of the brain and spinal cord and caloric stimulation have been explored as treatments.

The most common treatment plans involve a schedule of physical therapy with a medication regimen. Because the pain is mostly unchanging after development, many patients test different medications and eventually choose the regimen that best adapts to their lifestyle, the most common of which are orally and intravenously administered.

For acute pain, multiple medications given at the same time is proven to be most effective. This results in lower pain scores, provides greater relief, allows lower dosing (and side effects), targets different nerve pathways, and can be tailored to the child.

If non-pharmacological measures are not effective, medications may be tried.

- Non-steroidal anti-inflammatory drugs (NSAIDs) are typically tried first. NSAIDs have been shown to be more effective than placebo, and are usually more effective than paracetamol (acetaminophen).

- In severe back pain not relieved by NSAIDs or acetaminophen, opioids may be used. However, long-term use of opioids has not been proven to be effective at treating back pain. Opioids have not always been shown to be better than placebo for chronic back pain when the risks and benefits are considered.

- Skeletal muscle relaxers may also be used. Their short term use has been shown to be effective in the relief of acute back pain. However, the evidence of this effect has been disputed, and these medications do have negative side-effects.

- In people with nerve root pain and acute radiculopathy, there is evidence that a single dose of steroids, such as dexamethasone, may provide pain relief.

- Epidural corticosteroid injection (ESI) is a procedure in which steroid medications are injected into the epidural space. The steroid medications reduce inflammation and thus decrease pain and improve function. ESI has long been used to both diagnose and treat back pain, although recent studies have shown a lack of efficacy in treating low back pain.

Chronic pain is treated with a variety of medications and non-pharmacological interventions. Opioid tolerance and withdrawal can be seen in the NICU and PICU. Other side effects with opioid use can be: cognition deficits, altered mood, and disturbances of endocrine development. Opioid misuse can occur in adolescents and is associated with the use of alcohol, cigarettes and marijuana.

Non-pharmacological treatment for children in helping to relieve periodic pain episodes and severity includes counselling and behavior modification therapy. The American Association of Pediatrics have suggested that parents be educated on providing round the clock medication administration after their children receive surgery.

Psychological and social support has found to play a key role in the management of chronic illnesses and chronic pain conditions, such as trigeminal neuralgia. Chronic pain can cause constant frustration to an individual as well as to those around them. As a result, there are many advocacy groups.

Massage therapy using trigger-point release techniques may be effective in short-term pain relief. Physical therapy involving gentle stretching and exercise is useful for recovering full range of motion and motor coordination. Once the trigger points are gone, muscle strengthening exercise can begin, supporting long-term health of the local muscle system.

Myofascial release, which involves gentle fascia manipulation and massage, may improve or remediate the condition.

A systematic review concluded that dry needling for the treatment of myofascial pain syndrome in the lower back appeared to be a useful adjunct to standard therapies, but that clear recommendations could not be made because the published studies were small and of low quality.

Posture evaluation and ergonomics may provide significant relief in the early stages of treatment. Movement therapies such as Alexander Technique and Feldenkrais Method may also be helpful.

Gentle, sustained stretching exercises within a comfortable range of motion have been shown to decrease pain thresholds. Regular, non-intense activity is also encouraged.

There is little research on treatment for phantom vibrations. Carrying the cell phone in a different position reduces phantom vibrations for some people. Other methods include turning off the vibrate mode or using a different device.
